Question

ОДНА СТОРОНА ПРЯМОУГОЛЬНИКА 1ДМ.ЭТО НА 7СМ БОЛЬШЕ ЕГО ДРУГОЙ СТОРОНЫ.УЗНАЙ ПЛОЩАДЬ ПРЯМОУГОЛЬНИКА.

Answer 1

1 сторона - 1 да = 10 см
2 сторона - на 7 больше = 10 + 7 =17
S = 10 × 17 = 170 см

Answer 2

1 дм-10 см
1)10 -7=3
2)10×3=30

Answer 3

Finding the Length of the Rectangle's Sides

To find the length of the sides of the rectangle, we can use the information given: one side of the rectangle is 1 dm longer than the other side, and the longer side is 7 cm longer than the shorter side.

Let's assume the shorter side of the rectangle is represented by a and the longer side is represented by b.

From the given information, we can set up the following equations: - b = a + 1 dm - b = a + 7 cm

To solve for a and b, we can equate the two equations: - a + 1 dm = a + 7 cm

Since the units are different, we need to convert them to the same unit. Let's convert 1 dm to cm: - 1 dm = 10 cm

Now we have: - a + 10 cm = a + 7 cm

By subtracting a from both sides, we get: - 10 cm = 7 cm

This is not possible, as it leads to a contradiction. Therefore, there seems to be an error in the given information. Please double-check the values provided.

Calculating the Area of the Rectangle

Since we were unable to determine the lengths of the sides of the rectangle due to the contradictory information, we cannot calculate the area of the rectangle accurately.

However, if we assume that the shorter side is a and the longer side is b, we can calculate the area using the formula: Area = a * b.

Please provide the correct values for the lengths of the sides of the rectangle so that we can calculate the area accurately.
